Black & Decker 20 V 1.5 Ah Battery Pair

This kit supplies two 20 V 1.5 Ah lithium-ion batteries built for the Series 7720 cordless drill. They power a 20 V motor that delivers up to 30 N.m of torque across 21 plus 1 clutch settings. The pack suits homeowners and DIYers who need a ready spare for continuous drilling and driving tasks.

Thermals Noise and Power Draw

Lithium-ion cells run cool during typical use and the drill’s two speed ranges of 0 to 400 RPM and 0 to 1500 RPM keep current demand moderate. No fan is present so operation stays quiet while the 1.5 Ah capacity supports extended work sessions without excessive heat buildup.

34 Piece Accessory Bundle

The included case holds 4 wood bits, 4 twist bits, an extension bar, a flexible shaft, 10 short screwdriver bits, 10 long screwdriver bits and a screw anchor set. These pieces cover common drilling, driving and fastening jobs so the kit works straight from the box without extra purchases.

Questions about this item

How do I install the 20 V 1.5 Ah lithium-ion batteries into the 7720 series drill driver?

Align each battery with the slide rails on the handle and press firmly until the latch clicks; the step people miss is fully seating both packs before the first charge.

What maintenance or replacement will the 2 x 1.5 Ah lithium-ion packs need over time?

Expect capacity to fade after several hundred charge cycles; store at room temperature, avoid full discharge, and replace both packs together when run-time drops below useful levels.

Which limit appears first during sustained use of the 20 V motor with 30 N·m torque and two speed ranges?

The 1.5 Ah packs will deplete before the motor overheats, especially at the 0-1500 RPM setting under the full 266 in-lb load.
